Bottom-trawl and gill-net data from the Upper Great Lakes, collected by R/V Cisco, 1952–1962
The data release includes part of the bottom-trawl and gill-net survey data collected between 1952 and 1962 from the research vessel R/V <em>Cisco</em>. The bottom-trawl dataset includes tables for fishing operations and effort (BT_OP.csv), fish catch (BT_Catch.csv), and individual length-weight-sex-maturity (LWSM) records (BT_Fish.csv) for only a subset of species (details below). The gill-net dataset includes tables for fishing operations (GN_OP.csv), fishing effort (GN_Effort.csv), fish catch (GN_Catch.csv), and individual LWSM records (GN_Fish.csv) for only a subset of species (details below). Two reference tables, BT_Spec.csv and Species.csv, are used for bottom trawl specifications and fish species names, respectively.<br />
<br />
This data release is part of the project "Historical habitat use by <em>Coregonus artedi</em> in the Upper Great Lakes and critical embayments" funded by Environmental Protection Agency's Great Lakes Restoration Initiative. Due to the scope of this project, the catch tables (GN_Catch.csv and BT_Catch.csv) only include data for alewife (<em>Alosa pseudoharengus</em>), rainbow smelt (<em>Osmerus mordax</em>), and cisco (<em>Coregonus artedi</em>). LWSM data tables (GN_Fish.csv and BT_Fish.csv) only include data for cisco. Additional data collected from the surveys are archived at the Great Lakes Science Center.
